Fourth quarter 2020 adjusted EBITDA is expected to be approximately $55 million. The Company expects fourth quarter 2020 adjusted diluted loss per share to be approximately ($0.85). “Flat-rolled customer demand in the U.S. and Europe has improved throughout the fourth quarter, fueled by consumer-driven end-markets such as automotive, appliance, and packaging,” commented U. S. Steel President and Chief Executive Officer David B. Burritt. “December’s performance has been particularly strong driven by the flow- through of higher steel prices, more nimble operations, and a continued focus on cost management. As a result, we have line of sight to significantly improved financial performance in 2021. Longer lead times, higher utilization rates, and higher input costs reflect current healthy steel demand and make us optimistic about the sustainability of today’s market environment.” Adjusted EBITDA Commentary Our Flat-rolled segment is expected to generate positive EBITDA in the fourth quarter. Our order book remains strong across key strategic markets and higher steel prices are being more fully reflected in our adjustable contract business. This market backdrop informed our decision to restart blast furnace #4 at Gary Works and iron ore production at our Keetac mine to ensure we continue to satisfy strong customer demand. We expect to benefit from improved efficiencies as we exit the year. In Europe, customer demand continues to be strong. Improved commercial performance and a focus on cost management are expected to more than offset raw material headwinds from higher iron ore prices. As a result, fourth quarter results should exceed third quarter performance.

Higher rig counts are not yet resulting in higher shipments as distributors manage inventories into year-end. We remain focused on what we can control, including the start-up of our electric arc furnace (EAF) at Tubular where we produced first rounds for seamless pipe production at the end of October. The in-sourcing of rounds production is already beginning to improve the segment’s cost structure in the fourth quarter.

©2019 U. S. Steel. All Rights Reserved NEWS RELEASE www.ussteel.com Note Regarding Non-GAAP Financial Measures We present adjusted net earnings (loss), adjusted net earnings (loss) per diluted share, earnings (loss) before interest, income taxes, depreciation and amortization (EBITDA) and adjusted EBITDA, which are non-GAAP measures, as additional measurements to enhance the understanding of our operating performance. We believe that EBITDA, considered along with net earnings (loss), is a relevant indicator of trends relating to our operating performance and provides management and investors with additional information for comparison of our operating results to the operating results of other companies. Adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA are non-GAAP measures that exclude the financial effects of restructuring charges and other adjustments that are not part of the Company's core operations. We present adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA to enhance the understanding of our ongoing operating performance and established trends affecting our core operations, by excluding the financial effects of restructuring charges and other adjustments that can obscure underlying trends. U. S. Steel's management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA as alternative measures of operating performance and not alternative measures of the Company's liquidity. U. S. Steel’s management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA useful to investors by facilitating a comparison of our operating performance to the operating performance of our competitors. Additionally, the presentation of adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA provides insight into management’s view and assessment of the Company’s ongoing operating performance, because management does not consider the adjusting items when evaluating the Company’s financial performance. Adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA should not be considered a substitute for net earnings (loss), earnings (loss) per diluted share or other financial measures as computed in accordance with U.S. GAAP and is not necessarily comparable to similarly titled measures used by other companies. -oOo- 2020-043 Founded in 1901, the United States Steel Corporation is a Fortune 250 company and leading integrated steel producer.
